Description
Technical Field
The utility model relates to the field of nuts, in particular to a special nut assembly for a screw of a plate heat exchanger.
Background
In actual use, effective fastening of the screw and the nut is crucial to stable operation of the apparatus. Along with the large-scale plate heat exchanger, the screw nuts on the plate heat exchanger are gradually increased, and the sizes of some nuts reach M56. The larger the fastener, the corresponding torque value increases, and the large torque requires a large torque wrench or an additional force rod, which is a great challenge for field assembly and subsequent disassembly and assembly maintenance.
In the conventional process of locking the nut, the acting force of a worker on the nut needs to overcome the friction force between the nut thread and the bolt thread and the friction force between the end face of the nut and an object to be locked immediately before the locking end position, so that the worker needs to use larger torque. Because the friction between the nut threads and the bolt threads cannot be changed, the only way to reduce the acting force of workers when locking the nut is to reduce the friction between the end face of the nut and the object to be locked. Conventional nuts have no way of reducing the frictional force between the end surface of the nut and the article to be locked immediately before the end of nut locking. After the torsion of the nut during screwing is reduced, the problems of field assembly and subsequent disassembly and assembly and maintenance inconvenience are effectively solved.
Disclosure of Invention
In order to solve the defects in the prior art, the utility model provides the special nut component for the screw rod of the plate heat exchanger, and the component can reduce the friction force between the nut body and the surface of an object to be clamped, reduce the torsion force of the nut body during locking and facilitate the on-site assembly and maintenance work of workers by arranging the nut bearing.
The technical scheme of the utility model is as follows:
the utility model provides a special nut assembly for plate heat exchanger screw rod, includes the nut seat, one side of nut seat is equipped with the nut bearing, one side of nut bearing is equipped with the nut body, the nut seat includes bolt hole and dead eye, the dead eye is equipped with the nut bearing.
Preferably, a bearing screw hole is formed in the outer side of the nut seat, and a screw penetrates through the bearing screw hole to be connected with the nut bearing.
Preferably, a nut screw hole is formed in the outer side of the nut seat, and a screw penetrates through the nut screw hole to be connected with the nut body.
Preferably, the nut body is cylindrical, and the upper edge is provided with a nut notch, wherein the nut notch is along the radial direction of the nut body.
Preferably, the nut bearing is a thrust ball bearing.
The utility model discloses a during the equipment, at first will nut seat cover is on the bolt that corresponds, then puts into the nut bearing in the dead eye, later will the nut body is screwed up on the bolt, the workman can use tools to put into in the nut breach, it is rotatory the nut body reaches the installation the purpose of nut body.
The utility model achieves the following beneficial effects:
by arranging the nut bearing, the friction force between the nut body and the surface of an object to be clamped can be reduced, the torsion force of the nut body during locking is reduced, and the on-site assembly and maintenance work of workers is facilitated;
by arranging the nut notch instead of the traditional outer hexagon nut, the outer diameter of the nut during design can be reduced, and under the condition of uniform diameter, the locking example between the nut body and the bolt designed by the utility model is larger.

Detailed Description
To facilitate an understanding of the present invention by those skilled in the art, specific embodiments thereof are described below with reference to the accompanying drawings.
As shown in fig. 1 to 3, the utility model provides a special nut assembly for a plate heat exchanger screw, which comprises a nut seat 1, wherein a nut bearing 2 is arranged on one side of the nut seat 1, a nut body 3 is arranged on one side of the nut bearing 2, the nut seat 1 comprises a bolt hole 4 and a bearing hole 5, the nut seat 1 can be sleeved in the corresponding bolt hole 4 by arranging the bolt hole 4, and the nut bearing 2 is arranged in the bearing hole 5.
In this embodiment, a bearing screw hole 10 is disposed on the outer side of the nut seat 1, a screw passes through the bearing screw hole 10 to be connected to the nut bearing 2, and after the screw passes through the bearing screw hole 10 and contacts with the nut bearing 2, the nut bearing 2 is prevented from rotating, and thus the nut body 3 and the nut bearing 2 are prevented from relative displacement.
In this embodiment, a nut screw hole 9 is disposed on an outer side of the nut seat 1, and a screw passes through the nut screw hole 9 and is connected to the nut body 3, so as to lock the nut body 3 and prevent the nut body 3 and the bolt from sliding relatively.
In this embodiment, nut body 3 is the tube-shape, and the top edge is equipped with nut breach 8, nut breach 8 is followed the radial direction of nut body 3, through setting up nut breach 8, workman can use the instrument to drive nut body 3 is rotatory, and then accomplishes nut body 3 with the work is paid to the lock of bolt.
In the present embodiment, the nut bearing 2 is a thrust ball bearing, and the nut bearing 2 is axially rotatable around the bolt together with the nut when the nut body 3 rotates.
The utility model discloses a during the equipment, at first will nut seat 1 cover is on the bolt that corresponds, then puts into nut bearing 2 in the dead eye 5, later will nut body 3 is screwed up on the bolt, the workman can use tools to put into in the nut breach 8, it is rotatory nut body 3 reaches the installation nut body 3's purpose.
The utility model achieves the following beneficial effects:
by arranging the nut bearing 2, the friction force between the nut body 3 and the surface of an object to be clamped can be reduced, the torsion force of the nut body 3 during locking is reduced, and the on-site assembly and maintenance work of workers is facilitated;
